To summarise the article, the lightest shoe is the new Nike Free Run+ 2 and is closely followed by the Adidas ClimaCool Ride.

Hi ross88guy
your list is good but have you every looked at the K-Swiss Kwicky it weighs only 8.0oz and is great if you prefer to run sockless, also the K-Swiss K-Ruuz weighs 6.5oz, is a running flat which is great for speed work and racing.
